VEHICLE TIRE Filed' Nov. 1o. 1928 BY "ITORNEYS Patented July 28, 1931 PATENT ori-1er VINCENZO GASTORINA, OF XVEST NEW' YORK,`NEW JERSEY VEHICLE' TIRE Application filed November 10, 1928. Serial No. 318,430.

This invention relates to vehicle tires, and has as an object the provision of a pneumatic vehicle tire, which is substantially puncture proof, but which can be utilized 51 as a solid tire in the event of a puncture.L

According to this invention, the pneumatic tube is arranged in a chamber formed by an inner and outer strip of solid rubber mounted on the periphery of a metal rim lo. which is of hollow construction with its outer wall concave. The kouter strip is provided with a flexible metal liner which is effective to prevent the passage of nails or the like through the same. A thick rubber tread overlies the above mentioned outer strip and provides additional protection for the pneumatic tubeas well as acts as the wearing surface of the tire. he various elements comprising the tire are held on the rim by means of detachable arcuate members and make it possible to renew the tread member as it becomes worn, without necessitating replacement of any of the other parts.

The above described arrangement affords further substantial protection to the pneumatic tube against puncture while retaining thepneumatic keffect desirable for motor vehicles. However, should the pneumatic tube become deflated for any reason, the

tire may still be used. In such circumstances, the tread member and rubber layers ,are pressed against the met-al rim, but the outer surface of the tread member projects su'fliciently beyond the metal parts of the wheel to function in the manner of solid rubber tires. f

Other objects, novel features and advanf tages of this invention will be apparent from rthe following specification and accompanying drawings, wherein Fig. 1 is a side elevation of a wheel equipped with a tire embodying the invention.

Fig. 2 is an enlarged section through the rim of the wheelrk disclosed in Fig. 1, and

Fig. 3 is a similar section with the pneumatic tube deflated.

The wheel 10 is similar to the standard artillery automobile wheel and has mounted. 'i' thereon a rim 11 which is held place by the rim bolts 12. The rim 11, which is of hollowconstruction, is made concave along its periphery to provide an annular seat 13. A strip of Vsolid rubber 14lies in the seat 13 and is surrounded by a pneumatic Ltube 15 provided with a valve stem 16 which extends inwardly through both the strip 14 and the rim 11. l

A second strip 17 of solid rubber overlies the pneumatic tube 15 and has its edges in contact with the edges of the strip l14. These strips are held in assembled relation to the rim 11 by means of arcuate clamps 18having sockets to receive beads formedV on the edges of such strips, the clamping members being attached to the rim by bolts 19. A flexible metal shield 2O is carried by the inner face of the strip 17 andjhas its edges extending along the junction between the two strips 14 and 17, the strip 17 being cut away to permit easy movement of such edges. A thick solid rubber tready member 21 overlies the strip 17 and is provided with beads fitting into sockets in the clamping members 18 forholding the tread member in assembled relation to the remaining parts of the tire. i

The pneumatic tube 15 is rendered substantially puncture proof by the protection afforded by the thick tread member 21 and lthe metal shield 20. A short nail or the like cannot penetrate the tread 21 because of its thickness and a longer nail or the like will be turned away from the pneumatic tube by shield 20. However', should the air leak out of the pneumatic tube for any reason, the tire is still capable of being used. Under such circumstances, the various parts assume the relationship shown in Fig. 3, and the tread 21, together with the strips 14 and 17, constitute a solid tire upon which the wheel may run. The pneumatic tube will be held tightly between the layers 14 and 17 and will not bev harmed by the use of the tire, while the tube is deflated.

The above described tire will last practically indefinitely for as the tread 21 becomes worn it may be removed and a new tread substituted. The removal of this tread may be efected by' removing the clamping members 18, thus permitting disengagement of the same from the beads on lthe tread. After a new tread has been applied, the clamping membersmay be again 5 attached to the rim. Since the rim 11 is of hollow construction and its outer wall is relatively thin, it is somewhat resilient',

which adds to the riding qualtiesoawheel equipped therewith, especially should the 10 inner tube become deflated.. The` edges of the shield 20 rnovel laterally whenever the strip 17 is pressed inwardly thus preventing: buckling of the shield and permitting free movement of the same; y Y c 15 It is, of course, understood that various modifications-may be made in thelstructure= above described without inlany way departing from' the spirit of the invention: as d'e l device-ofthe character described, com-v prising af hollow riml having' a concave peripheral wall, a solid rubber strip lying' in'- the groove thus formed andl having beads y 253 overlying the" edges of the-v peripheral wall,
